COUPLING FOR ANTISKID-CHAINS. a

Application-filed October 17, 1919.

To all whom it may concern:

Be it known that I, PETER ARNoLTs, a citizen of the United States, residing in Odell, in the county of Livingston and State of Illinois, have inventedcertain new and useful Improvements in Couplings for Antiskid-Ohains, of which the followmg' is a specification. I

The object of this invention is to provide a simple and eflioient device for coupling the ends of antiskid automobile chains.

Ordinarily considerable effort is required to bring together the ends of such chains and much time is often taken in properly coupling them. i

- According to my invention the chains are provided with devices by means of which their ends maybe quickly coupled, tension being so applied as to hold-the chains sec'urely on the tire, and the chains are so loose.

In the accompanying drawings Figure 1 shows a side elevation of a part an automobile wheel having an 'antiskid chain applied to its tire, and equipped with my improved chain coupling.

Fig. 2 is a view on an enlarged scale and in side elevation of my improved chain coupling device, and indicates how it is applied to an automobile wheel equipped with an antiskid chain.

Fig. 3 is a perspective view of the coupling device.

The drawings show, in Fig. 1, a portion of a Wheel A, having a tire B carrying an antiskid chain O of well known construction. D indicates my improved device for coupling and fasteningthe ends of the chain.

The improved coupling comprises a link d, to which is hinged at one end a lever d means of which it is having its end bent to form an eye al by coupled or hinged to the end of the link (Z. The lever is also formed with a loop (Z adjacent the eye (Z and which has an arm (1' having a hooked end (Z The arm d has a double curve, as indicated, better adapting it to act as a lever and to assume the proper position to couple the ends of the chain. E indicates a lever locking device, comprising a cross piece e having at opposite ends eyes 6' through which the side portions of the link (Z extend. The locking device is adapted Specification of Letters Patent.

to slide on the link from end to end thereof. One end of the link, as indicated at w, is applied to one end of the chain C.

his connection is a permanent one and wien itis desired to connect the ends of the chain, the lever arm (Z is passed through the end link 0 of the chain in the Y manner indicated in Fig. 2. Then the lever arm ispressed down into the link cl in the manner indicated in Fig. 2 and also in Fig. 1. In this operation the two ends of the chain are mov'ed toward each other and placed under tension. When performing this operation, the locking device E is moved to one end of the link, away from the lever, so that the end of the lever may be passed through the link or into it. Then the locking device is slid along the side bars of the link'and passed over the hooked end of the lever, and is then moved backward a short distance until it engages the hooked end of the lever.

lVhen the hands of the attendant are released, the chain puts a tension on the coupling, and the locking device E is firml held in engagement with the hooked end of the lever.

I have shown one coupling device; where the chain is made in sections, similar coupling devices may be applied at the proper places.

It, will be observed that the cross piece 6 of the lever locking same plane with the two sides of the link (Z so that the hooked end of the lever lies Within the link when it engages the locking device. It will also be observed that the eye (Z of the locking lever is formed by bending the end of the lever which, as shown, is made of wire. The lever can therefore be readily applied to the link by merely bending its end around the end of the link and if the lever is broken a new one can easily be attached to the link. It will furthermore be observed that the loop (Z of the lever has its sides or arms substantially parallel with each other and when the lever is engaged with the device E these arms which are parallel with each other are also substantially parallel with the link so that when strain is exerted on the device it will be in a direct line as indicated in Fig. 1. In such case no strain is exerted on the locking device E but is transmitted through the shorter arm of the loop device lies in the V d directly to the link. This strain is endwise and not diagonal as it would be if the loop were otherwise formed.

Experience has demonstrated that the coupling device iherein shown and described operates aeliiciently; It is very simple in construction, may for the most part be made of wire, and may be easily applied and operated.

- I :as my 'invention::

A coupling and fastening device for antiskid chains comprising a Wire link, a wire lever having one end bent to form an eye to providera Eh'inge connection with one end end near the eye the sides. of the arms of which are substantially parallel with each other and with the sides of the link when in locked position, said lever being provided at its outer end with a hook and a locking device for the lever comprising a cross piece with \which the hooked end of the lever engages and which lies in the plane of the link and has eyes at opposite ends engaging the link;

In testimony (whereof, I have hereunto subscribed my name.
